Hey can somebody help me install sumo for vanet in ubuntu 10.10 (I'm using ns2
on this )
the method indicated at the website is too complicated ,
could anyone please explain me the code part of aodv
ACTIVE_ROUTE_TIMEOUT *
aodv.cc: // Set expiry time to CURRENT_TIME + ACTIVE_ROUTE_TIMEOUT
aodv.cc: rt0-rt_expire = CURRENT_TIME + ACTIVE_ROUTE_TIMEOUT;

Hi :I'm using the old trace format in ns2 ,I have an awkscript that is
calculating parameters for routing ,I am able to calculate all the dropped,send
and received packets ,but when I calculate pdf,and normalized routing load I'm
getting the error :

Hello all
I wanted to know if anyone has used trace2stats v0.5b awk scripts for
wireless formats, and if you can explain me the jitter file in it. I mean we
have 4 different values of jitter, and the calculations in the script dont
explain me fully which jitter you would look for finding out
How can I measure control overhead in ns2 for routing protocol comparison?I
want to compare aodv and dsr in terms of which protocol generates less overhead
.How can I do that?Should the overhead include AGT as well as RTR ?and what
about mac layer packets ?can someone describe that for me?and

then they decide which one to use.

how to use these scripts and can there be any other method to do this all
.thanks
Dear all,
I've read some research papers in which they compared performances of
different routing using some normal performance metrics, such as:
Packet delivery fraction
routing control overhead
Average end-to-end delay
Average number of hops

graph?
HI :
I still cannot run any wireless simulation ,and how to analyse simulation ?I

Hi
I could not simulate AODV and DSR successfully ,May be there are errors in tcl
files.can someone please tell me the authentic tcl file links that really work?
And please tell me how to analyse the simulation and calculate routing protocol
